Vacuum separation system

(1) Japanese three-dimensional thin film evaporation technology is introduced and it is composed of atomizer, reactor, separation chamber, fuel tank, aspirating chamber, foam breaker, inspection window and level indicator;

(2) Atomizer: atomize the oil in the vacuum separation system and spray onto the reactor;

(3) Reactor: composed of several lassig circles, making the oil mist sprayed onto the reactor to oil slick, volatilizing the moisture and gas in oil to the fullest extent and improving dehydration and degassing efficiency greatly;

(4) Separation chamber: located between the reactor and fuel tank. Water, gas and oil is separated again while oil is working within the area;

(5) Fuel tank: gather the oil separated from the water and gas and discharge from the oil drain pump;

(6) Aspirating chamber: extract the water vapor and remaining gas after being separated from the reactor and separation chamber from the vacuum separation system. Preventing the moisture and gas dissolved again in the oil;

(7) Foam breaker: Korean AUTONICS infrared ray device is applied to remove the oil vacuole generated in the oil automatically in place of manual removal, realizing unattended operation;

(8) Inspection window: tempered glass is used for inspection glass to replace the organic glass which will be depressed and deformed under the condition of high temperature and high vacuum;

(9) Automatic level indicator control device (infrared ray and stainless steel electrokinetic transducers are adopted for double level controlling) is equipped to guarantee the automatic balance adjustment of the filling and discharging oil and the constant oil filter system working different on condition of men-machine;

(10) Duplex three-dimensional evaporation structure is applied to expａnd the evaporation area greatly, extend the evaporation duration of the purification oil in vacuum separation system and improve the efficiency of dehydration (free water and moisture) and degassing greatly.

Condensation system

(1) The unique technique of our company: heat exchange condensation technique;

(2) The condensation through optimized designing increases the heat radiating area to the fullest extent, condensing the moisture discharged from the vacuum separation system, preventing large quantities of water vapor from entering the vacuum pump directly, emulsifying the vacuum pump oil to spray and extend the service life of vacuum pump;

(3) Determine whether the moisture contained in the purified oil has completely removed or not.

Filtering system

(1) Multiple stages filtering is adopted: German HYDAC Technology GmbH is used for filter element. The filter fineness of primary filter which is made of stainless steel for filtering the iron impurities is 80μm. The filter fineness of the second stage filter, which is made of stainless steel wire and supports recycle use after being cleaned, is 20μm. The filter fineness of secondary filter, the filter element flux of which is 20 times of the rated flow, is 5μm. Even though most part is blocked, fluent oil filtering can be guaranteed.

(2) Overpressure alarming and shutdown device (measuring the pollution level of the filter element) is equipped to prevent damages of the filter wire due to overpressure, which reduces the cost, guarantees the safety of filter system and reminds the operator of cleaning the wire in the meantime.

(3) Pressure controller is applied for alarming element to guarantee the stability of performance of alarming and shutdown.

(2) Overpressure and shutdown device for outlet pressure is equipped and the technique index is in accordance with the national standards;

(3) Tool cabinet is provided in the electronic control cabinet for keeping tools and information;

(4) Oil pump and heater are interlocked to guarantee that the heating power is automatically off while the oil pump stops working due to accidents;

(5) Vacuum pump and heater are interlocked to guarantee that the heater cannot work until the oil enters the heater after the vacuum pump is enabled;

(6) Intelligent display temperature controller is adopted. Such controller, which is in high reliability, is available for minimum and maximum temperature settings to avoid constant enabling of the heater and extend the service life of electronic appliance;

(7) Overload protection and thermal relay protection is equipped;

(8) The control layout is easy for reading and operation. The buttons include main power switch, vacuum pump enabling and stopping, oil pump enabling and stopping, heating enabling and stopping with indicator light displaying;

(9) The machine is provided with phase sequence and default phase protection;

(10) The perfect interlocking installation guarantees the reliable operation of the complete machine for a long time;

(11) Standard trunking is applied for the wiring in the electronic control cabinet to guarantee the wiring neat while cable is adopted for the exterior line of the electronic control cabinet and iron plastic pipes are installed for protection.
